'VIBRA'IOB, FOR PRIBTIING EB-ESSES.

Application filed October 13, 1921. Serial No. 507,488.

To all whom, it may concern:

Be it known that I, ARTHUR J. DAANE, citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Vibrators for Frint'ing Presses, of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

The invention relates to ink distributing rollers for printing presses,and particularlv to a means for quickly and conveniently permitting theattachment and removal of the device to and from the printing press andto provide a construction whereby this may be accomplished withoutnecessitating any change to be made to the press.

it is an object of the invention to provide a construction capable ofperforming the above advantages which is simple and effective inconstruction and operation which may be reniovably clamped to the inkingroll frame which in one type of press carries the inking rolls andtravels in planes across the platen and type, this portion to which thedistributing roll is reinovably attached being termed the sad dle. V

It is a further object of the invention to provide a construction whichis movable outwardly relatively to the ends of the dist-rilnitingroller, so that it may be arranged in this position to permit of itsattachment or release with respect to the saddle.

it is a further object to provide the device with means for releasablylocking the parts against accidental release whennssociated for use withthe press.

In the particular embodiment or structure employed for accomplishing thedesired advantage one of the elements is movable outwardly with respectto the ends of the distributing roller, so as to permit this part tobearranged to allow the end of the roller and the device to beassociated with the saddle. Upon the release of this movable portion,the saddle is engaged, and this portion engages certain other parts ofthe construction, in which position it is releasably locked againstaccidental separation.

The invention will be explained in conjunction with the a companyingdrawings in which various structures are illustrated,

it being, therefore, obvious that other changesand modifications may beresorted to without departing from the spirit of'the appended claimsforming part hereof.

In the drawings, Figure 1 is a side elevation of a portion of theprinting press having one embodiment of the invention ap- V pliedthereto.

Figure 2 is an elevation partiallyiin section of an ink distributingroll showing the embodiment of the structure shown in Fig ure 1. v

Figure 3 is an end view of the structure shown to the left of Figure 2.

Figure 4c is a view showing one of the structures employed in Figure 2,in changed position.

I Figure 5 is an end elevation of the structure shown at the right ofFigure 2.

' Eigure 6 is a sectional view of a'modifiedarrangement which may beresorted to showing a changed position in dotted lines.

Figure 7 is an end elevation of another structure which may be employedto accomplish the invention.

Figure 8 illustrates a tensioning device for the ink distributingroller, which may be applied to the end of the previous structures.

Figures 9, and 10 illustrate further construction which may be employedto accom-V plish the invention.

In the embodiment of theinvention illustrated in Figure 2 the use of aroller 10 is contemplated which reciprocates longitudinally of the shaft11. This roller cooperates with the usual inking rollers of the pressand due to its reciprocation evenly distributes the ink upon theaforesaid rollers thereby insuring even distribution of ink upon thetype.

The means whereby this device may be attached to a printing presswithout necessitating' any changes being-made to the press or the use ofany tools to effect its attachment and release, is generally desig nated12 and consists of two members, 13 and 14, which are designed to embracethe saddle 15 of the press to hold the ink distributing roller withrelation to the press. The member 12 is bent to form the right angleportions 16 and 17, the end of the portion 16' being bifurcated toprovide the arms l8-18 between which themember 13 is pivotally mountedso that it may swing outwardly with respect to the shaft 11 when theparts entering into this'const-ruction are arranged to permit of this.

The downwardly extendmg portion 17 of the member 12 is provided with aslotted aperture18 which redeives the shaft 11 and permits it toreciprocate with respect to the member 1% to thereby compensate forvarious shaped surfaces over which the inking rollers of the presstravel duringtheir movement relative to the platen-of thepress and thetype.

The shaft'll extends beyond the downwardlv extending portion lTof themember 12 and slightly beyond the swinging memer 13 and is provided witha head 19. and

V a reduced or neck portion 20, the reduced portion substantiallycorresponding in dimensions to'a reduced portion of a slot provided inthe member 18 in which the shaft is mounted for reciprocation. This slotis designated 21 and is provided with an enlarged portion with which theend of the shaft is brought into juxtaposition thereby permitting themember 13 to be disconnect ed from this end of the shaft. 11 when swungoutwardly. This enlarged portion of the slot permits the connection ofthe. swinging member 18 when the latter is swung inwardly and theenlarged end of the slot and end of the shaft are again brought intoregister.

This member 13 is provided with a handle or finger piece 28 to assist inswinging the member 13 outwardly. A coiled spring 24lis provided whichengages this member 13 adjacent the handle and acts to swing thelowermost portion of the member 13 inwardly when the pressure upon thehandle 23 is released, the coiled spring being arranged upon the pinwhich passes and the roller 10in close contact with the inking rolls andsaddles of the press yet permits it to yield 01' reciprocate within theslots 18 and21.. I I I 1 The lowermost end of the member 13 is Iprovided with an inwardly projecting lug which has a curved surfacewhich when the device is arranged in proper relation withrespect to thesaddle of the press, is permitted to engage one of the lower faces ofthe saddle and allows the device to rock with relation to the saddle. A.portion of the arm 17 engages one side face of the saddle,. the member13 the opposite side and the end. of the shaft. is arranged. adjacentthe uppermost face thereof, consequently the shaft 11 is arrangedadjacent the portion 16 ofthe member 12. This brings the extreme end ofthe shaft having the head 19 and the neck 20 into relation with theenlarged' portion 22 ofthe slot 21 so that an inward pressure applied tothe finger piece 223 permits the lowermost end of tlie member 13 to beswung outwardly away from the end of the shaft which disassociates thesemembers and permits the entire device and the inking roller to be liftedaway from the press.

To effect a connection of the roller and this element and the press thedevice will be arranged above the saddle and pressure again applieduntil the. extreme end of the shaft is brought into alignment with theenlargedopening 22 ofthe aperture 2lcf the member 13' and by virtue ofthe action of the spring. 24 the member 13 is moved toward the extremityof tlieshaft over the head 19. V r

Upon the release of the downward pressure heretofore referred tothemembers 12 and 13 are moved upwardly and the shaft is moved in theopposite direction by means of the spring 29 causing the shaft 11 toassume a position adjacent the lowermost extremity of the slot 21. Byvirtue of the shape of the extremityv of the shaft 11 and the slot withwhich it is atthis time in 00 operative relation, the parts are lockedtogether so that accidental separation thereof is prevented, it beingunderstood that at this time the inward extension 30 is in engagementwith the lower face of the saddle.

The member 18 may, if so desired, be provided with the lugs 31 wh ch aredesigned to engage the side faces of the portion 33 of the saddle Fromthe description of thls structure it is evident that a simple andBITQCUXGVIHGELDS ink distributing roller to a printing press withoutnecessitating. any change or addi-' tion to be made to the press whichis a material'advantage as'iteliminates much un necessary labor.

It is understoodthat the opposite ends of the shaft are provided with astructure similar to that just described, however, pro

vision may be made to permit the connec-- tion vof a device of thischaracter with the press despite the fact that the swinging frameof'most presses 0f the Gordon type are provided with a pin whereby thepressman may manually lift or lower the inking rollers when this isfound necessary or desirable. To accommodate this structure the .isprovided for attaching and removing an swinging member 13 will beprovided with a cutout portion 34 which will readily pass over this pinor a structure similar to it which allows the device tobe attached orremoved with relation to the press without hindrance by this pin. 3

In the structure illustrated in Figure 6, a slightly differentarrangement is provided. In this embodiment of the invention theclamping element, generally designated 35, is also movable outwardly andinwardly with respect to the end of the vibrator shaft to effect aseparation and connection of the device and the press.

To accomplish this result when a structure similar to that illustratedin this embodiment of the invention is employed, the plunger 36 and themember 35 are movable together longitudinally of the shaft of thevibrator in the slot 37 provided in the vibrator shaft.

A coiled spring 38 is confined in this slot 37 and this spring reactsbetween the end of the slot and the reduced portion 39 of the plunger.The plunger is provided with an enlargement 40 at its lowermost end andthe fact that the remainder of the plunger 36 is of a greater dimensionthan the slot prevents the separation of the plunger and the shaft, butpermits the plunger to slide longitudinally within the slot 37. Themember 41 in this structure is provided with a slot 41 within which theend of the vibrator shaft is mounted for reciprocation with relation tothe niember'4l. This slot also permits the member 35 and the plunger tobe moved longitudinally of the vibrator shaft so as to position themember 35 to allow it to engage and release the saddle of the inkingrollers of the press.

The inwardly projecting portion 42 of the member 41 is provided with ahousing 43 within which is confined a coiled spring 44 which acts uponthe plunger 36 in a manner similar to that described with relation tothe structure disclosed in Figure 1, and allows the plunger to be movedwith relation to said bracket.

From the description of this structure it is evident that the plunger 36and the member 41 may be moved together endwise or longitudinally withrelation to the end of the shaft which permits the device to bepositioned to allow it to engage and releasethe saddle of the printingpress when manipulated to accomplish this result.

The shaft of this structure has a pin 45' projecting from the undersurface thereof which is provided to engage the innermost face of thesaddle.

The member 41 is also provided with an inwardly projecting lug 46 andthe lugs 4747 which respectively engage the under and opposite sides ofthe projection 33 of the saddle. This structure may also be providedwith a cut away portion 48, the

function thereof being similar to the portion 34 shown in Figure 2.

It is manifest that this structure is also capable of effecting anassociation and release of the distributing roll and press by theapplication cf an outward pressure upon the memberor 41 which willposition the parts to allow the device to be associated and disconnectedrelatively to the press. Upon the applieation'of this pressure theinwardly projecting lugs 46 and 47 are positioned relatively to thesaddle so that by a downward pressure upon the member 35- the lugs 46and 47 will be broughtto a position in which the may engage the lowerface of the saddle. pon the release of the outward pressure upon theseaforesaid ele' ments the spring 37 causes said lugs to pass below thelower face of the saddle andupon the release of the downward pressureupon the member 35 the coiled spring 44 is permitted to act which bringsthe lugs into engagement with the underside of the saddle and the shaftinto engagement with the upper face thereof. 7 V

To effect a separation of the structure after it has been applied, allthat is necessary is to apply anoutward pressure to the plunger 36 orthe member 35 and its associated mechanism This causes'a disconnectionof the lugs 46 and 47 from' thesaddle which allows the entire mechanismtobe lifted away from the press.

In the structure shown in Figure 10 the vibrator shaft is provided withtwo pins which when the device is arranged for cooperation with thesaddle of the press, are

disposed upon opposite sides of the swinging portion of the structure.This allows the shaft to reciprocate in its slot the lat-- ter beingenlarged at its uppermostend to allow the swinging member to be moved beyond the end of the shaft.

All of these structures, heretofore explained, may, if so desired, beprovided with. a means for regulating the tension of the spring whichacts upon the plungers such as 36 which are connected to the shafts ofthe distributing roller. To accomplishthis advantage the outer face ofthe housings for the spring will be provided with screw threads 53 andarranged in threaded rela tion to the portion carrying the housing. Byrotating the housing by means of the head 54, said housing will beadjusted and vary the tension of the springs confined therein. V with aset nut 55 to lock the housing in its adjusted position with relation tothe particular element with which it is associated.

In the structure illustrated in Figures 9 and 10, the swingingportions-are pivoted to the shaft at 56, and arranged to swing from thispoint as a pivot. The structure of This structure may be providedFigure}? is slightly different from that of Figure 10 in that avertically arranged pin 57 is carried by the swinging member This pin 57enters an aperature 59 in the shaft of the vibrator. This end of theshaft is'arranged forreciprocation with respect to the pin 57 and theslot 60. 7

To disconnect the means of this structure, the shaft willbemoved-toassume the dotted line position shown. This allows the member58 to be swung outwardly upon the pivot 56 causing the disconnection ofthe parts and allowing eitherthe association or removal of this devicefrom the saddle or" the printing press. v

From the foregoing description o-it the Various structures, it isevident that a simple and effective arrangement is produced whereby anink distributing roller may be releasably connected to the frame of aprint ing press by a movement which is endwise I of the distributingroller shaft; also that provision is made: whereby said roller may bemoved with relation to the saddle during its travel with the inkingrolls of the press without resulting in a disconnection or the devicewhereby the distributing roller and the press are connected together. Itis further evident that the device may be attached to a printing'presswithout necessitatingany change whatsoever to be made in theconstruction of the press, despite the fact that in some instances a pinor other projection is a part of the printing press structure.
